The reason why Guangdong men are infected: Because novel coronavirus can spread through contact, infected people in the same unit sneeze or cough in the elevator, which may pollute the elevator buttons and other places. If a healthy person doesn't wash his hands in time after touching his eyes or mouth, he will be at risk of infection, so these coincidences just happened to be met by this man.
The reason why men in Inner Mongolia are infected: At present, it is initially thought that the droplets generated by patients chatting at the door of infected people are converted into aerosols and floated to the infected people's homes, which leads to infection, or because the droplets left by infected people are attached to the door of infected people, just touching the virus when closing the door, and then rubbing their eyes and mouth to get infected.
If an easily infected patient happens to be walking in the sun on the roof or outdoors in bask in the quilt, the droplets when she sneezes are likely to attach to the quilt, so the quilt is a terrible source of infection at this time. Many people will say, can't the sun kill the virus? Even though COVID-19 will be killed by high temperature and ultraviolet rays after exposure, why not bask in the quilt?
We all know that COVID-19 will die under high temperature and ultraviolet rays, but it takes 30 minutes at 56 degrees Celsius. In winter, the outdoor temperature of our sunshine can't reach 56 degrees Celsius in any case, so even a day's exposure can't kill the virus left on the quilt.
Don't count on the ultraviolet rays in the sun, because that little ultraviolet ray is not enough to kill novel coronavirus. The official ultraviolet sterilization method can only use professional ultraviolet lamps for sterilization.
Even if our quilt prevents the infected person from sneezing, there is still the risk of infection when we hold the quilt up and down the stairs or take the elevator. Now is a special time, we are afraid of 10,000 just in case, so try not to go to bask in the quilt in public.
However, there are exceptions to everything. If you have an independent yard at home, you can often do laundry and go to bask in the quilt, so don't consider the above modes of communication. Regular washing clothes and bask in the quilt can reduce the growth of other bacteria and viruses, which is good for us.
Summary: The epidemic situation is still very serious. With the backlog of patients in Wuhan and other places receiving treatment one after another, we are likely to reach the peak of the epidemic in February, but as long as our people unite as one, no matter how big the difficulty is, it will be insignificant if it is divided by 654.38+0.4 billion. Come on, Wuhan and China! ! !
The epidemic in novel coronavirus has not passed yet, and many friends feel that many things in their daily lives have been affected. For example, a friend asked such a question. Can bask in the quilt dry clothes outdoors during the epidemic? I believe this problem still cannot be generalized, but should be analyzed in detail.
Judging from the behavior of drying clothes and quilts, this is actually a positive prevention and control behavior in novel coronavirus. Ultraviolet rays in the sun are a kind of rays that can effectively kill novel coronavirus. If it is possible to expose clothes, quilts and other items that come back from going out to the sun, it will be a good behavior to prevent the spread of novel coronavirus.
But when you say drying quilts and clothes outdoors, I don't know whether you mean drying them on your balcony or in your yard. In both cases, you can avoid drying clothes and bedding within 2 meters without touching strangers. You fully support drying clothes and bedding when the sun is shining. In fact, if you don't sterilize your family's coat in other ways, it would be nice to catch up with the sun.
However, for friends who live in urban residential buildings, there is a common situation, that is, because the balcony is closed, some friends will dry bedding or clothes on the public facilities downstairs. If that's the case, it's not recommended that you do this in your daily life, because after all, public areas are not where you dry clothes, and it's not recommended that you do this in the current epidemic situation.
Although the public facilities downstairs in the community are well ventilated places, the ultraviolet rays in the sun still have a certain sterilization effect, but the current situation of epidemic prevention and control is still relatively complicated. In this case, it is difficult to ensure that there will be infected people passing through the public facilities outside the building, or that the droplets of the virus will pollute the dry items. If the bedding and clothes are contaminated by the virus, there is no guarantee that they will not be transmitted to people. In the process of going up and down stairs, taking elevators and opening and closing building security doors, there is no doubt that the risk of virus infection on hands or drying items will increase. Therefore, this outdoor drying method is not recommended. Clothes and bedding that need to be aired should be aired on your balcony. At the same time, you can pay attention to keep ventilation. This is much safer than taking things to outdoor public areas to dry.
Regarding the epidemic prevention and control of this new virus, I suggest that you should not be too scared and lead to excessive caution, but you should also pay enough attention to it and do a good job of protection. The best epidemic prevention strategy is to balance the two. For example, in the case of drying clothes, if you have the conditions, it is of course no problem to dry clothes outdoors in your yard. If the virus may spread in the circulating air at any time, then we will not recommend that you open windows frequently at home during the epidemic prevention period. It is often ventilated, so the air in your yard to dry clothes is no different from the air in your home when you open the window, so there is nothing to worry about. However, if clothes and bedding are dried in public facilities outside residential buildings, the probability of virus transmission and infection will increase to some extent under the current epidemic situation, so I suggest that you do not do so.
During the epidemic period, it is certainly possible to dry clothes and bask in the quilt, because there are ultraviolet rays in the sun, and ultraviolet rays have a very strong bactericidal ability, so it is very necessary to dry clothes and quilts regularly during the epidemic period.
However, when drying our clothes and quilts, we need to pay attention to the following problems, especially now is the critical period of epidemic prevention and control:
1. Try not to dry clothes and quilts outdoors: especially people who live in buildings can dry clothes and quilts on balconies and rooms facing the sun. People in rural areas can dry clothes and quilts in their own yards.
2. The place to dry clothes should be in a place where there are few people: some people in rural areas may go to the central area of the village to dry clothes, which may lead to direct contact with others, droplets, sneezing and other pollution of clothes and quilts, leading to the spread of bacteria and viruses. Secondly, in urban communities, there may be more clothes to dry at the bottom of community buildings, which is also not recommended.
3. Grasp the drying time: Many people think that the longer the quilt and clothes are dried, the better. In fact, the drying time can be controlled at 1-2 hours, and it can be dried from 2 pm to 4 pm, because 2 pm to 4 pm is the time when the sun is concentrated and the light is strongest.
4. When drying clothes indoors, you should open the window for ventilation: not only outdoor fresh air can flow in, but also dust on clothes and quilts can flow out, thus avoiding irritation to respiratory tract and nasal cavity.
In a word, during the epidemic, we shouldn't panic too much. As long as we follow the advice of medical staff, take corresponding protective measures, stay indoors and do a good job of isolation, we can prevent the infection of germs.
Recently, the number of people suffering from new pneumonia is still increasing, so everyone is inevitably panicked. They can only stay at home and try their best to keep themselves away from the virus. But when the weather is fine, they inevitably want to go out to bask in the sun. They also want to bask in clothes and quilts. So, during the novel coronavirus epidemic, can they go to bask in the quilt?
You can go to bask in the quilt during the novel coronavirus epidemic, but it depends on the situation. If you are in the countryside and have your own big balcony, you can bask in the sun if you want, and you can also disinfect the quilt clothes.
Studies have also proved that novel coronavirus is sensitive to ultraviolet rays and temperature, and can be inactivated in 30 minutes at 56 degrees, so its viability is not very strong. Sunbathing in a quilt can play a better role in killing viruses.
However, if you are in a city with dense floors, you should consider whether the quilt will be polluted by droplets. We still don't recommend bringing quilts to the public to dry in this special period. As long as you pass this time, you won't have a chance to go to bask in the quilt.
If the weather is fine and you really want to bask in bask in the quilt, you might as well put the quilt on your balcony and put it on the rope. The best time in bask in the quilt is from 6:438+00 am to 2: 30 pm. You'd better take a shot when collecting. If it is dirty, you'd better hit it with a stick or something. When you are in bask in the quilt, you can turn it over in an hour or so, so that both sides of the quilt can be dried. Duvets can also be placed on indoor chairs, as long as they can be ventilated.
In this special period, it is suggested that everyone should go out as little as possible, stay indoors and be isolated at home. If you need to go out when necessary, remember to wear a mask and wash your hands frequently when you get home. At the same time, if you have the conditions, you should wash your hair, bathe and wash clothes in time.

From the physical and chemical characteristics of coronavirus, we can know that the virus is sensitive to ultraviolet light and heat. In other words, when the virus is in the sun, its pathogenicity and survival time will be greatly reduced. Moreover, in a well-ventilated outdoor place, there is basically no risk of infection due to drying clothes and bask in the quilt, so you can rest assured that the weather will be fine.
However, it should be reminded that although there is no risk of infection in drying clothes outdoors and bask in the quilt, it is necessary to take precautions when going out. The transmission in COVID-19 is mainly droplet transmission and contact transmission, so it is best to wear a mask all the time. When taking the elevator, disinfect it with paper towels or alcohol, or put on disposable gloves and press the elevator button. Don't touch your mouth, eyes and nose with your hands. Wash your hands immediately after you go home.
Don't trust information from unknown sources easily, and everything is subject to official notification; When I am free now, I just have time to do something I am usually interested in; If you have bad emotions such as worry and fear, you can tell your relatives and friends around you to ease your emotions; If the situation is serious, you can consult a psychologist. In addition, if you have respiratory symptoms such as fever, cough and expectoration, don't worry, you can consult the doctor in the local hospital online first, and then go to the hospital for examination if necessary.
Hello, everyone, I'm a physician. As we all know, China is now waging a war without smoke, and the whole people are mobilized to participate in the war, which means "epidemic prevention war". Due to the different epidemic situation in different parts of the country, the epidemic prevention measures adopted are also different. For example, in our community, outsiders are not allowed to enter, and only one representative can go out to buy daily necessities and food every two days. Some readers think, if the sun is so good, can it kill novel coronavirus in the sun?
In fact, with the popularization of science, many people know that fat solvents such as ultraviolet rays, hot water above 56℃ for 30 minutes, 75% alcohol, chlorine-containing disinfectants, ether and peracetic acid can kill viruses, so if you have any of these substances around you, you can use them for wiping and disinfection.
Seeing the anti-virus measures I mentioned above, many netizens may think, ultraviolet rays? This is part of the solar radiation, so we can kill novel coronavirus by spending more time in the sun. In fact, this view is wrong. Although novel coronavirus is sensitive to ultraviolet rays and heat, it can't reach 56℃ even in hot weather in summer in China, so it is not advisable to kill the virus by the temperature of the sun. This is one of them. Second, although there are ultraviolet rays in the sun, they are not enough to kill novel coronavirus, and ultraviolet rays in the sun can easily cause skin damage if exposed for a long time. Of course, the biological effects caused by ultraviolet radiation in different bands are also different, and China is currently in winter and spring, and the clear Wan Li has not yet arrived, so it is not appropriate to use temperature or ultraviolet rays.
(2) When it comes to drying clothes in bask in the quilt, I think we should treat it rationally. I have made a general introduction to the ultraviolet rays in the sun above. Because the intensity of ultraviolet rays is influenced by many factors (solar height, latitude, cloud cover, altitude, ozone, ground reflection, etc.). ), if the weather is fine, just take it out and kill and disinfect it, except for mites, but it is unrealistic to expect to kill novel coronavirus with ultraviolet rays. When drying clothes and quilts, I suggest that it is better and more hygienic to dry them on my balcony. If you take them to public areas and cross other people's homes, it is always better to pay attention to them.
3 dry goods: What I want to talk about next is actually the most important content today. Ultraviolet rays can really kill novel coronavirus, but we must use the right method. This involves an indispensable thing, namely "ultraviolet lamp", which can completely kill novel coronavirus through the irradiation of ultraviolet lamp. In other words, masks and protective clothing are in short supply, but I think ultraviolet lamps still exist. Shopping online is also very convenient now, and the prices are different. Can be purchased according to personal needs. Put the ultraviolet lamp in a relatively closed place, then put the clothes and quilts that need sterilization and disinfection indoors and disinfect them for half an hour.
Everyone must adjust their mentality. Although we are in the epidemic stage, it does not mean that novel coronavirus is everywhere in the air, and the route of aerosol transmission has not been confirmed by the National Health and Wellness Committee and the CDC recently. Therefore, residents in non-epidemic areas should not bear too much psychological burden, as long as they do personal protection (wash their hands frequently, wear masks, eat safely, go out less, etc.). ), I don't think the problem is big. To borrow an old saying, for this virus, we! !
The epidemic situation in COVID-19 is still developing, with 597,465,438+0 confirmed cases and 65,438+06067 suspected cases as of 8: 00 am on February 4, 2020. Although it has been strictly controlled for a week or two, the data show that the number of cases is still increasing and many people are still infected.
First of all, we know that COVID-19 can spread from person to person, and the spread usually occurs in the crowded areas of families, workplaces or hospitals. Because there is no effective treatment at present, prevention and isolation are the most effective methods to minimize the contact opportunities of infected or potential infected patients.
For people living in urban communities, I don't recommend outdoor bask in the quilt. First of all, many communities don't provide outdoor places to dry things, so you may need to pull the rope to dry them yourself. If you occupy the main passage of the community, it will affect the passage of residents in the community. Secondly, although residents' access is strictly controlled, there are still many residents who need to go out for shopping because of the shortage of daily necessities, and the virus may spread back and forth through their quilts. If the weather is really not suitable for bask in the quilt, it is suggested that residents in urban communities can sunbathe on balconies or sunny places, and there is no need to take the risk of going downstairs to sunbathe outdoors.
For rural residents, most residents have a large area of open space at their doorsteps. If the open space is not a main road, and there are not many pedestrians or vehicles passing by, this kind of playground meets the conditions of outdoor drying. Moreover, rural residents are all family members, and there is a distance between them. The adjacent open space can be counted as their own safety range. Similarly, if a family is infected, the adjacent open space should also be counted as an infected area.
For special treatment in special period, the drying time should not be too long. It is best to dry in high temperature and sunny days, and it is best to dry at noon 1 1: 12 to 2: 00 pm. It's better to bask in bask in the quilt during this period. Because long-term outdoor drying will increase the chance of exposure to the virus, so try to choose a short time and sunny time to dry.
Spring returns to the earth, the sun is shining, and everyone has the habit of bask in the quilt. But in the face of the epidemic, although the sun is shining, there are many hidden worries in bask in the quilt. We are afraid of cross infection. Can I go to bask in the quilt? If you are infected with the virus, you don't have to taste it. Personally, I think so, but you must bask in your own balcony, not in the yard, because there is a risk of infection with the virus. I bask in my balcony, which is empty and there are no outsiders. The quilt is also disinfected by ultraviolet rays, so I will stay on my balcony in bask in the quilt. However, after all, it is an extraordinary period, so we should pay more attention to prevention and do not recommend frequent bask in the quilt.
The most worrying thing for everyone these two days is to hear that the virus can spread through aerosols. On February 8, a press conference was held in Shanghai. Zeng Qun, deputy director of Shanghai Civil Affairs Bureau, said at a news conference: Health and epidemic prevention experts stressed that the transmission route of pneumonia infected in COVID-19 can be determined by aerosol transmission. As soon as the news was announced, many ordinary people who didn't understand the principle were so anxious that they didn't even dare to go out or go to bask in the quilt for fear that the virus would spread through the air. In order to let you know more about aerosol transmission and relieve your anxiety, Dr. Wu will talk to you briefly about this problem.
Aerosol can be simply understood as a substance smaller than a droplet when people sneeze, cough or speak. Because droplets are relatively large in diameter and heavy in weight, they spread violently in a short time, and they can only be infected through direct contact. Aerosol is much smaller than a liquid drop, and its weight is very light, as light as a "cloud", so it can be suspended in the air for several hours. In closed or semi-closed spaces, such as elevators, cars, offices and other places with poor ventilation, if there are novel coronavirus patients, there may be aerosols discharged from the air by patients, and if healthy people inhale air with high aerosol concentration, they may be infected with novel coronavirus. This is the so-called aerosol propagation!
In fact, aerosol propagation must meet two conditions: one is confined space, and the other is aerosol density. Only in the air of a confined space can aerosol of a certain concentration be gathered, and only aerosol of a certain concentration can infect others.
For outdoor environment, aerosol can not form a threatening concentration, and of course it is impossible to infect people. In fact, there are all kinds of viruses in our air. The reason why these viruses don't cause diseases in our bodies is that outdoor air dilutes these viruses so that they don't form a threatening concentration. For example, a drop of ink can make a can of water black, but if you drop a drop of ink into a big river, it won't cause any change at all! So you don't have to worry about going out to bask in the quilt at all.
The most important thing to prevent the virus from spreading through aerosol is to pay attention to confined spaces, such as indoors, elevators, buses, etc. Especially in confined spaces with large flow of people. When entering these spaces, pay attention to wearing masks for protection, and pay attention to ventilation and ventilation in these spaces to avoid increasing aerosol density. If possible, the air in these spaces can be disinfected. Doing these things well can prevent the virus from spreading through aerosols.
We all know that the transmission route of this new virus is droplet transmission and contact transmission, and it is said that aerosol can also spread. If you want to dry clothes and quilts outdoors, you need to see if there are other people passing by in bask in the quilt. If it is your own yard, bask in the quilt and clothes are safe outdoors. If you live in a residential building without your own yard and everyone is together in bask in the quilt, it is relatively unsafe. If you want bask in the quilt and clothes, you can only do this.
Novel coronavirus, namely "20 19-nCoV", is copied by RNA, so ultraviolet lamp is useful for it. This COVID-19 is afraid of ultraviolet rays. We can use ultraviolet rays to kill viruses, which is also a good choice. After going home, take off your coat and trousers and put them in a ventilated place to dry. It would be better if there was enough sunshine.
If home conditions permit, ultraviolet rays can be used to disinfect the surfaces of rooms and clothes. If disposable masks are not enough, you can also use this method for simple disinfection, but if disposable masks are reused, you must use your own masks and don't mix them. Of course, the most effective prevention method is to stay at home and not go anywhere.
One thing to be reminded is that when using ultraviolet rays, you must be careful about the damage of ultraviolet rays to the skin and eyes. Don't stay in the room when turning on the ultraviolet light in the room, and then enter the room after turning off the ultraviolet light. Because ultraviolet rays are very lethal to bacteria and viruses, they also do some harm to human body, especially to our eyes. So don't look directly at the ultraviolet light when you turn it on.
If you don't have your own single-family house, a balcony with ventilation and sunshine, or an ultraviolet lamp, it's cheap and safe to open the window to blow.
